In the present study the obtaining of biodiesel was investigated using ashes from the banana peel of Musa x paradisiaca L of the variety "valery" as a catalyst in the transesterification of used vegetable oils. Both the ripe banana peel and the used vegetable oil were collected in the university cafeteria. Used vegetable oil was previously treated to eliminate impurities and moisture present through decantation, filtering and drying operations. The values of humidity (0.42%) and degree of acidity (0.27%) obtained in the analysis of the used vegetable oil determined to carry out a direct transesterification reaction. The ripe banana peels were cleaned and selected and then dried at a temperature of 80 ° C for 48 hours, then they were pulverized and calcined at 700 ° C for 4 hours obtaining the CCPC catalyst, in them the amount of potassium was determined (515.02 mg / Kg) and calcium (41.14 mg / Kg). Using in the transesterification 4% of the catalyst with respect to the weight of the oil, alcohol / oil molar ratio 9/1 and reaction time 90 minutes, a maximum yield of 90.17% was achieved and when 2% of catalyst was used, a yield of 89.33 in% biodiesel. The ANOVA statistical study showed that there are no significant differences (p˃ 0.05) when using both percentages in the transesterification reaction. By means of the mid-infrared spectroscopy analysis (FITR-ATR-PLS) the presence of the functional group ester was confirmed and the maximum value (91.565% m) in content of methyl ester (FAME) in the biodiesel obtained. The study concluded that the calcined banana peel ashes showed great potential to be used as a catalyst in the production of methyl ester from used vegetable oils, due to the high content of potassium in its chemical composition that gives it a base character. strong.
